The species of the genus Xiphinema Cobb, 1913 are listed and their current status is indicated. A revised polytomous key to the 172 valid species (excluding the X. americanum-group) is presented. Because of the very large number of species the key is split into eight groups on the basis of development of the anterior female genital branch, uterine differentiation and tail shape. In accordance with the opinion of Cohn & Sher (1972) X. vulgare Tarjan, 1964 is considered a synonym of X. setariae… 
A revised polytomous key for the identification of species of the genus Xiphinema Cobb, 1913 (Nematoda: Longidoridae) with exclusion of the X. americanum-group: Supplement 1
Codes are given for eleven Xiphinema species described since the new polytomous key (Loof & Luc, 1990) was submitted plus one species described earlier but which had not come to the authors' notice.
A revised polytomous key for the identification of species of the genus Xiphinema Cobb, 1913 (Nematoda: Longidoridae) with exclusion of the X. americanum-group: Supplement 2
TLDR
Thirty-one species and one subspecies have been described since publication of the first supplement to the polytomous key to Xiphinema spp, and 13 are considered valid, for which identification codes are given.
A revised polytomous key for the identification of species of the genusXiphinema Cobb, 1913 (Nematoda: Longidoridae) with exclusion of theX. americanum-group: Supplement 2
Thirty-one species and one subspecies have been described since publication of the first supplement to the polytomous key toXiphinema spp. (see Loof & Luc, 1993). Of these, 11 species belonging to

Examination of paratypes of five species of Xiphirzemn from India described by Singh and Khan (1998) led to the following conclusions: X. lnrlinni Khan & Singh, 1998 appears a valid species close to
Cryptic diversity and species delimitation in the Xiphinema americanum-group complex (Nematoda: Longidoridae) as inferred from morphometrics and molecular markers
TLDR
Integrative taxonomy, based on a combination of multivariate morphological and molecular analyses constitutes a new insight into the identification of X. americanum-group species.
A new species of the genus Xiphinema Cobb 1913 (Nematoda: Longidoridae) from north and northwest Iran
TLDR
Five populations of a new dagger nematode species were recovered from natural grasslands and forests of north and northwest Iran, and described based upon morphological and molecular data in present paper, which is similar to six known species belonging to artificial morphospecies group 5.
Description and molecular characterisation of Xiphinema herakliense n. sp. (Nematoda: Longidoridae) from wild and cultivated olives in Crete.
TLDR
The results of the phylogenetic analyses based on the sequences of the D2-D3 expansion regions of the 28S rRNA gene and ITS1 rRNA genes are supportive of the specific status of the new species.
Description of Xiphinema castilloi sp. n. (Dorylaimida: Longidoridae) from Iran and its phylogenetic relationships
TLDR
By having two equally developed genital tracts, presence of pseudo-Z-organ, and similarities in tail shape of females and juveniles, the new species comes more close to X. dentatum, another member of morphospecies group 5.
Xiphinema bernardi n. sp. (Nematoda: Longidoridae) from the Great Smoky Mountain National Park.
TLDR
Molecular approaches using the internal transcribed spacer 1 sequences of nuclear ribosomal DNA suggested that X. bakeri and X. diversicaudatum are the most closely related species from the species examined.
Molecular and morphological characterisation of Xiphinema granatum n. sp. and Longidorus pisi Edward, Misra & Singh, 1964 (Dorylaimida: Longidoridae) from Iran
TLDR
The new species is characterised by presence of sperm in the female genital tracts, uterus devoid of any Z-differentiation or spines, and abundant males with spicules 45-58 μm long.

TLDR
The validity of groups and more particularly the subgenera of Xiphinema created by Cohn ad Sher (1972) are discussed and the characters of these 74 species are assembled in a “lattice” permitting a more easy and rational determination than keys or tables.
